My GS1000 isn’t charging put a new stator on hasn’t made any difference, old stator has 2 wires new one has 4 any ideas 

 

best regards

Odd! All 3 phase alternators usually have 3 output wires - sure one hasn't broken off hence why not functioning?

I always change the Regulator/Rectifier when I lose either of these parts, as they seem to take each other out.  I have presently been the Voltage Regulator Rectifier for Yamaha YZF-R1 2002-2014 FZ-1 06-14 FJR1300 motorcycles.  It only cost me $28 dollars, and shipping was free.

 

One thing  to note, one many Suzukis, they rectified the voltage to D.C., but only regulated 1 leg of the stator, allowing the voltages on the other two legs to swing up and down wildly.  This has killed so many Suzuki motorcycles.  Whatever you do, make sure you get a R/R that rectifies and regulates all 3 stages of the stator.  It will save you much grief.  Don't get the O.E.M. one.

Can you expand on that, Ian?

Are you asking me? Having  "Duh" moment. ;)

Suzuki used an Alternator-Generator.  The created electricity(AC) by induction passing coils.  The regulator monitors alternator output voltage/current and controls alternator field current accordingly..  The 2 legs that converted AC to DC were left to swing, and often one leg lead up to the headlight which would be able to take that kind of chaos.  Since the bikes have 3 wires coming out of that contraption, it's best to use a fully regulated/rectified AC to DC Reg/Rec unit.  Nothing has to be changed.  I pulled all 6 feet of that wiring out of my harness, and ran the stator directly to the (at the time) Kawasaki XS1100 Rec/Rec and the DC output directly to the battery.  The wires were less that 10 inches long from the DC output to the battery.  This made sure that battery got the load completely, as motorcycles run off of the battery, not the alternator, or alternator/generator, whatever the case would be. A poorly designed system.

If any vehicle has a pure generator, it can be bump started, and the generator, which is producing a lot of DC will let the vehicle run, still you shut if off, or it if it charges the battery after a very long ride, (generators are usually 10 lbs. or 15 lbs. heavy and very long), which is why they stopped using them.  They were useful for hooking up to an inverter and making A/C.  All my old Volvo's had real generators in them.  They never broke down, and could be made into bicycle powered DC supply units.
